The New York State Sewersheds shapefile is a GIS layer that contains estimates for every municipal sewershed in New York States as of November 2022 with estimated populations higher than 100 persons. For data on sewersheds with fewer that 100 persons, please contact the author. Each sewershed is a georeferenced polygon for the estimated boundary of all parcels of land that are connected to the public wastewater treatment plant and the sewers flow into the common point, which is the treatment plant’s location. Please include the citation below when using these data.
